Ebola outbreak in West Africa (2013-2016)
An original outbreak of Ebola virus disease that begun in West Africa in December 2013, mainly affecting Guinea, Liberia and Sierra Leone has now ended but the risk of sporadic cases (flare-ups) remain. On 8 August 2014, WHO had declared the Ebola epidemic in West Africa a Public Health Emergency of International Concern (PHEIC).
The WHO declared the end of Ebola transmission in Guinea on 29 December 2015, in Liberia on 14 January 2016, and in Sierra Leone on 17 March 2016.
WHO continues to stress that the countries are still at risk of sporadic transmission of Ebola, largely due to virus persistence in some survivors, and must remain on high alert and ready to respond. Strong surveillance and emergency response capacity need to be maintained, while care, screening and counselling also need to be provided for survivors.
According to WHO on 18 March 2016, a flare-up of Ebola cases was reported in a rural village in the prefecture of Nzérékoré, Guinea.
